ROSE PLANT Filed Oct. 18, 1965 United States Patent O 2,463 ROSE PLANT Emest Schwartz, Kingsvifle, Md., assignor to The Canard; Pyle Company, West Grove, Pa., 3 corporaflon 051 Pennsylvana V Filed Oct. 18, 1963, Set. No. 317,393 1 Claim. (Cl. Plt.l)

The present invention relates to a new and distinct variety of rose plant of the shrub class, which was originated by me by crossing the variety White Dawn (unpatented) With the variety Pinocchio (Plant Patent No. 484).

As the result of this breeding, I have produced a new and improved rose variety Which is endowed with the following outstanding characteristics which distinguish the same from its parents, as well as from all other varieties of which I am aware:

(1) A compact and bushy habit of growth, With a gradually spreading habit which makes the plant equally suitable for hedge or ground cover purposes;

(2) Glossy, disease resistant foliage, Which makes the plant especially valuable for maintenance free plantings;

(3) Outstandingly good floriferousness and continuity of flowering;

(4) A habit of bearing the fiowers in clusters;

(5) A distinctive and attractive White flower color;

(6) A slight, spicy flower fragrance; and

(7) A winter hardiness which is superior to the average rose variety grown in West Grave, Pennsylvania.

In comparison with its .seed parent White Dawn, the new variety produces a more compact bush, With more foliage; it produces more blooms than this parent by reason of the fact that all of the flowers are borne on the current years Wood; while the flowers are not as large as those of this parent, they occur in greater number in each cluster; and the new variety is superior in resistance to mildew and blackspot.

As compared With the pollen parent Pinocchio, the new variety grows in a form suitable for either a ground cover or a shrub, as distinguished from the floribunda habit of this parent; it is more fioriferous; the flowers are white in color, as distinguished from those of Pinocchio which have a pink tint or blend; and the new variety is endowed With superior winter hardiness.

Asexual reproduction of my new variety by budding shows that the foregoing characteristics and distinctions corne truc to form and are established and transmitted through succeeding propagations.

The acompanying drawing shows typical specimens of the vegetative growth and flowers of my new variety in diterent stages of development, as Well as a typical blooming hedge planting illustrative of the spreading habit of growth, all as depicted in color as nearly truc as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new variety, With color terminology in accordance with the Horticultural Color Chart of the Royal Horticultural Society, except Where general color terms of ordinary dictionary significance are obvious:
